JAMES T. ANDREW, OF MONTGOMERY, ALABAMA.

SAFETY APPLIANCE ESPECIALLY ADAPTED FOR LOCOMOTIVES.

To all 'whom 15 may conce-rn Be it known that I, Jantes T. ANDREW, a citizen of the United States, residing at Montgomery, in the county of Montgomery and State of Alabama, have invented certain new and useful Improvements in Safety Appliances Especially Adapted for Locomotives; and l do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to railway safety appliances, and has for its object to produce a device of this nature which will be especially applicable to locomotives, and will serve to prevent the same from leaving the track when accidents are met with which would ordinarily cause disastrous results.

lVith this and other objects in view, the invention consists in the novel details of construction and combinations of parts more fully hereinafter disclosed and particularly pointed out in the claims.

Referring to the accompanying drawings forming a part of this specication in which like numerals designate like parts in all the views Figure l is a diagrammatic elevational view of a portion of the framework supporting a locomotive and its coacting parts, with my attachment applied thereto; Fig. 2 is a diagrammatic cross sectional view of a portion of the parts shown in Fig. l; and, Fig. 3 is an elevational view in perspective of a special chair or casting employed to connect my attachment to the framework of the locomotive.

l indicates the usual wheels and drivers of the modern locomotive; 2 a portion of the framework thereof comprising the longitudinal bars 3 and Li; 5 the axle of the drivers l;

-6 the brake shoes applied to said drivers;

and the brake beams for supporting said shoes.

8 represents a casting preferably of the shape shown in Fig 3, and provided with the lugs 9 and 10 forming the channel 1la therebetween, as well as the lug ll coacting with the base portion l2 forming the channel 13 therebetween. The frame member 3 is adapted to iit the channel 11a, and suitable bolts 14 are passed through the holes l5 in order to secure said frame portion 8 in said channel lla. Like bolts may be passed through the holes 1G in order to secure the frame member t in the channel 18, where- Specication of Letters Patent.

upon the whole casting 8 will be firmly secured to the engine frame. In order to supply additional bracing means, I have further provided the bent rods 20 which pass through lugs 21 secured to the frame me1nber i and pass over lugs 22 secured to the frame member 3, all as will be clear from Fig. l. The cast or forged supporting members 8 are preferably located between the framework 3 and 4, and the said bent rods 20, as indicated in Fig. l. rThe said members S are provided with the sector shaped openings 25 into which lit the cylindrically shaped supporting members QS ext-ending underneath the engine frame from side to side and from say six or eight inches beyond the drivers il. The said members 26 are provided inside the members 8 with the collars 2T which may be secured to said members Q6 in any suitable manner, as by the pins 28. The said members 27 are provided with iianges located about six or eight inches inside the iianges 30 of the drivers l, and the parts are so located and proportioned that the under surface 3l of the said members Q6 will rest a short distance above the top surface 32 of the rails 33. The said cylindrical supporting members 26 ar loosely fitted in the sector shaped openings Q5, so that they may freely rotate therein when their outer surfaces 3l are`brought into contact with the top surfaces 32 of the rails 33.

The operation of my improved safety device for locomotives will be clear from the foregoing, but may be briefiy summarized as follows :HShould the locomotive leave the track for any cause, say on the right hand side of the rails, as seen in Fig. 2, then the extending portion 'of the supporting members 2G will contact with the rail 32, on the left. of Fig. Q, and the portion of the said member 26 between the driver l and the collar Q7 on the right of F ig. 2, will contact with its corresponding rail, so that the locomotive will still be supported by the said members 26. The momentum of the locomotive, of course, will carry it along a certain distance, and the said members 26 will rotate in their bearings 25, until the engine is stopped either through the friction engendered, or preferably by the automatic application of the air brakes, in a manner not illustrated in this case, but fully disclosed in my prior patents relating to the same general subject.

An important feature of the resent construction resides in the fact t at by sup-- rea ily apply my improvement to modernengiiies without reorganizing or interfering with thel present construction of Atheir frameworks and coactin parts. It is especially important that te said members 8 are of the U-shape shown,l in order that the brake beams 7 may be readily accommodated between the drivers, as well as my supporting members 26.

It is obviousthat those skilled in the art may vary the arrangement of parts as well as the details of construction, without departing from the spirit 'of my invention, and therefore, I do notpwish to be limited to the above disclosures, except as may be required by the claims.

l. In a railway safety appliance, the combination of a supporting frame; wheels associated with said frame; su porting chairs provided with slots locate between the axles of said wheels; brake beams passing through said slots; and supporting members adapted to contact with the rails in case of accident, carried by said chairs, substantially as described.

Q. Iii a railway safety appliance, the coinbination of a su porting frame; wheels associated with said frame; supportin chairs provided with channels fitting sai frame and with slots located between the axles of said wheels; brake beams passing through said slots; and supporting members extending be ond said w eels adapted to contact with tie railsin case of accident, carried by said chairs, substantially as described.

3. In a railway safety appliance, the combination of a locomotive provided with a frame and a plurality of drivers mounted on-V axles; a channeled supporting chair secured to said frame between a pair of said I axles and provided with an o ening; a brake beam passing through sai opening; means com )rising lugs on said f rame for bracing sait chair; and a supporting member carried b saidchair adapted to contact with the rai in case of accident, substantially as described.

In a railway safety appliance, the combination of a locomotive provided with a frame, and a plurality of drivers mounted on axles; a supportinor chair secured to said frame between a pair of said axles and provided with an opening; a brake beam passing through said opening; means cornprising lufrs on said frame for bracing said chair; anda a sup orting member carried by said chair exten ing under said frame and beyond said drivers at each side and adapted to contact with the rail in case of accident, substantially as described.

In testimony whereof, I aiiix my signature, in presence of two witnesses.
